Abstract (en)

[origin: EP0843394A1] An ignition coil device, which is mounted in a plug hole of an internal combustion engine, comprises a primary coil 1 wound to have larger diameter, a secondary coil 2 wound on a bobbin 2A and disposed inside the primary coil 1, an iron core 3 disposed inside the bobbin 2A, and a shielding case 10 disposed around the primary coil 1, a gap between the primary coil 1 and the secondary coil 2 being filled with an insulating resin 12. The primary coil 1 is made bobbinless so as to secure and increase the withstand voltages of the primary coil and the secondary coil. <IMAGE>
